IMPROVEMENT IN SLED-RIVERS,

TO ALL WHOM IT MAY CONCERN: I

Be it known that I, JOHN W. BLAKE, of Jefferson, in the county ofJefferson, and State of Wisconsin,-

have invented a new andusefnl Sled-Knee for sleighs or sleds; and I dohereby declare that the following is a full and exact descriptionthereof, reference being had tothe accompanying drawing, making part ofthis specification, in which Figure 1 is the section of the sled-kneecomplete.

Figure 2 is a section showing lower shoulder and extension of theupright.

Figure 3 is a section of the upright, withzagas-pipe around it; and AFigure 4 is the side elevation of the plate D'and the runner.

The nature of my invention consists in a metallic sled-knee, consistinof an upright and a brace, so corn bined with the foot and beam-platesas to form a perfect device to securely bind and hold together therunner, beam, rave, and bolster-block, as will be hereinafter fullyexplained.

To enable others skilled in the art to which myinvention appertains toinakc and use said invention, I will proceed to describe itsconstruction and operation.

A is an inclined upright, provided with a shoulder, A, its extension, a,passing through and'beyond plate E, and shaped into a screw-bolt.

B is a brace, welded, or secured in any other way, to the upright, A, ata po D, andbent at the plate E, its extension, I), passingthrough andbeyond said plate, and shaped also into a screw-bolt, both extensions,(1 and b, bein so bent above the plate E as to form right angles withits upper or fitting-fare.

D is a i'oot-plate, provided with flanges d d, to enclose the runne isprovided with holes 0 O, forthe bolts to secure it to the runner. It maybe cast'around the foot of the upright, A, or may be madeseparatcly,-and 'set on thc'upright, A, in which cases the upright isprovided with another shoulder, a, as on fig. 2, and extends downthroughthe plate and intothe runner, being shaped into a screw-bolt toreceive the nut r, countersunk in the runner R, and being bent so as tohave this downward extension, 2:, at right angles with the lower orfitting-face of the plate D. I v

E is a beam-platc, cast around the upright, A, at its shoulder A, andaround brace B at its bend, or may be made separately, and set loosely'on the same.

Instead of making the upright, A, thicker between the plates D and E,'it may be mad ness all through, as on fig. 3, and passed through asleeve, F, of a gas-pipe or steam-pipe shape, fittin'g between theplates D and E, and forming shoulders for the same to rest upon or abutto. More braces, B, can be used with the upright, A, if it is necessaryor desirable. Beam G, rave H, and bolster-block I, are provided withholes, for the screw-bolted extensions, a and b, to pass through andreceive nuts N N.

It is seed from the above that the sled-knee described, made of metal,and arranged in the manner shown, forms a perfect bending-device tosecure and hold together the runner, ,beam. rave, and bolster of a sled,being at the same time durable and cheap. I

What I claim as my invention, and desire to secure by Letters Patent, is

The metallic sled-knee, consisting of the upright, A, and brace orbraces B, with their extensions, a, b, latesD and E, in themanner-herein shown int just above the foot-plate r R, and counteract alateral thrust, and

e of the same thickand specified, the whole arranged and operating asand for the purposes set forth.
